Frankel-Shibasaki烯丙胺芳基反应

铬催化中间体【Cr(CO)3】下，酚丙胺立体选择性的亚胺为酚胺的中间体。中间体常用的溶剂是萘。共轭二酚丙胺则暴发1,5-H迁移得到共轭酚胺。

另外Noyori手性催化中间体剂催化中间体下酚丙胺可以亚胺为手性酚胺。

中间体机理

中间体操作

Methyl N-(E)-5-(methoxycarbonylpentenyl)-N-(1E,3Z)-pentadienyl carbamate (5). A mixture of diene 4 (26.9 mg, 0.1 mmol), Cr(CO)3 (2.72 mg, 0.02 mmol), naphthalene and Me2CO (1 mL) was degassed through four freeze-thaw pump cycles, stirred for 4 h at 20 C and concentrated. Silica

gel chromatography afforded 23.1 mg of 5 (86%).
